android calendar helpSupport

I have had the evo for several months now and have still not been able to figure out how to do this. with two jobs and going to school full time my calendar is quite busy. I would like to make it so each job and school show as different colors when you look at my calendar so at least at a glance I can see what i have going on for the day. I know I could do this with my old blackberry, but is it possible with the Evo? any help would be greatly appreciated
